Grass raster to ArcInfo grid?

The ArcInfo command "imagegrid" has the option to import GRASS raster formats.
However, this appears to be only Grass3.1 format. We were working with a
ArcInfo 7.1. Is there any way to convert from Grass 4.1 to 3.1 formats? Is there
another way to get Grass raster formats into Arc Grid?
